You're only allowed to have one account. I think cross-site trading is allowed with other sites that allow it?

@Valtien Thank you! It's weird that the rules are kinda scattered about the site. It's definitely be nice for them to all be in once place, like in the ToS, or a separate link at the bottom for rules/conduct, since that's where they usually are.

As a majority of the people above mentioned, you’re only allowed to have one account, though multiple people can have the same IP address as long as there’s no evidence of multi-accounting. Cross-site trading, in case you didn’t know by now, is currently available only to Patreon supporters, so if you want to trade, you need to become a Patron to support the game. Just thought I’d clarify.

I forgot to mention it in my post, but DraconicMusic meant that the PC/item sending feature is currently only available to patrons, since it's in the testing phase. However it's possible to use your usershop to trade, but this isn't as secure.
